The stem is constructed with a bead, b, at its upper end, and is so connected at its lowereud to the plate 1),-thnt the stem and plate are free to turn independently of'cnch other.

The operation is as follows:

Thestopper being in the position represented iu tig. 2, is inserted into the bottle. The stein is then drawn outward from the neck by suitable machinery, the

body of the stopper beingheld so as vto prevent it from When the heed b has been Ydrawn quite out of the` recess "a, it is turned at right angles to its former posit-ion into the position .shown in figs. 3 and 4. By drawing out the stem, the

rubber is compressed in the direction of its length :md expanded laterally, so as to press tightly against the inside ot' the neck oi' the bottle, and'by turning -t-he head, the rubber is prevented t'rom resuming its former When the. vliquid is to be poured out, the bottle is opened by turning the head into the position shown in tig. 2, which at once releases the rubber'and allows thestopperito be withdrawn.
